Calgary Flames forwards Daymond Langkow (neck) and Matt Stajan (shoulder) will be out action for an indefinite period of time, the club announced Monday.

Langkow suffered a season-ending neck injury in March. He has skated with the club during the pre-season, but has yet to be cleared for contact.

The 26-year-old Stajan suffered a separated shoulder against the Vancouver Canucks on the opening night of the pre-season.

Additionally, wingers Rene Bourque and Raitis Ivanans missed practice on Monday for general maintenance resulting from recent training and competition.

This is good news, not for them, but for Backlund and David Moss. I'm assuming they'll be centering the second and third lines, with Conroy or someone centering the fourth. It's tough to see Langkow not recover from that neck injury. If he goes long term, then I guess we can clear him off the cap until he comes back.
